ULT:Balli-VIOLET?v LAMP APPARATUS.

Application filed April 14, 1926. Serial No. 101,849.

is capable of wider use than in the case ofv previous ultra violet lamp equipments. Previously, such apparatus was adapted for use in doctors otces or in hospitals, and the equipment provided for this purpose was excessively heavy, awkward to use, and extremely fragile. The object of my invention is to provide an apparatus of this kind which may be used by the patient himself, and which is so constructed that the delicate electric lamp, etc., used therewith is protectedirom damage while in use, as well as when not being used. A further object is to arrange the electrical equipment therein in such a manner that when not in use it is entirely protected from view. Further objects of my invention will appear from the detailed description ot the same hereinafter.

Vxlhile my invention is capable of embodiment in many different forms, by way of illustration I have shown only one form of the same in the accompanying drawings, in which- Figure 1 is a perspective view of an apparatus made in accordance with my invention, showing the same in a position for use;

Figure 2 is a perspective view of the same showing the apparatus when not in use; n y

Figure 3 is a vertical sect-ion of the apparatus; and

Figure 4 is a perspective view of the frame used for supporting the lamp.

In thedrawings I have shown a cabinet 1 made of metal or any other suitable material which is supported at its lower end upon a pair of large wheels 2 carried upon a fixed axle 8, and a smaller pair of wheels 4 carried upon independently movable pivots 5, so as to facilitate the movement of the apparatus in any direction, as desired. Above the wheels 2 and 4 there is a partition 6 to provide a compartment 7 in which there is carried any desired auxiliary electrical apparatus 8, as, for example, a transformer for changing from indirect to direct current, resistance coils, etc. The electrical apparatus 8 is connected with any suitable source of current by means ota lead 9 having a socket l0 to be inserted 1n any suitable source of electric current. The lead 9 passes out of the apparatus through a removable horizontal partition 11 which covers the auxiliary electrical apparatus 8, and is rendered accessible for connection to the source ot electric current when two front doors 12 and 13 on the apparatus are thrown open. IVhen the said doors 12 and 13 are open there is also accessible a manual switch 14 which is connected by a lead 15 through the partition 11 to the said apparatus 8.

Passing downwardly through the partition 11 there is also a rectangular conduit 16 supported by a bracket 17 from the rear wall of the cabinet. This conduit 16 has sliding within the same a telescoping conduit 18 which is adapted to be held in any adjusted position by'means of a hand-wheel 19 screwthreaded in the conduit 16. At its upper end the conduit 18 supports a reflector 19FL which is in the form of a part of a cylinder with a curved rear portion 2O and two ilat ends 21 and 22. The two ends 21 and 22 are provided respectively with pivots 23 and 24 in the form of bolts secured to the ends. 21 and 22 to support a rectangular trame 25 having secured thereto an electric lamp 26 made of quartz or otherwise adapted for emitting ultra `violet rays, by means ot straps 27, 28 and 29. The lamp 26 receives its current from leads 30 and 81 which extend down through the telescoping conduit 1 8 to the auxiliary electrical equipment 8. It will be noted that the trame 25 at one side of the same is provided with a hook 32 and that the 'frame at the other side of the same has a slot 38 so that in supporting the apparatus the lamp 26 may he tilted at will to cause a circuit to be initially completed therein through a body ot mercury contained within the same. Once the circuit is completed the frame 25 resumes its original position and the rays are produced within the vacuum therein without the liquid mercury completing the circuit between the terminals of the lamp. yIt will be noted that, as shown in Figure 1, when in use the reflector 19a is ordinarily raised into a position above the level at the top of the apparatus by throwing back a cov-er 3a which is hinged to the cabinet 1 in such a manner as to protect the electric lamp at the rear, the said cover 34 being supported in y this position by means of linked-arms 35 nd 36 at the two sides of the apparatus respectively. When the apparatus is not in use it will be understood that the reiiector 19"L sind the lzunp carried therein Will he inoved down to e position within the cabinet l, the plug l0 Will be Withdrawn from the source of electric current7 and the leads il und 9 will be placed in the cabinet l upon the transverse partition ll, whereupon the doors l2 and 13 will be closed und the cover 3 lowered so that the parte are entirely eneloied and protected 'troni dani-rige', etc., is shown in liligure 2. in this position the apparatus may he used :is it bedside table or :in :uixilizlry table wherever desired.

lv'hile l have described iny invention miic-ve in detail l wish it to be understood that nniny changes may be ine-de therein without departing from the spirit of the saine.

I claim:

l. In combination, an electric lmnp adapt ed to emit ultra violet rays, a cabinet enclosing the sinne, and a slide for guiding the lmnp upwardly from Within to a position above the seine, said slide having therein electrical connections for the lamp.

2. ln coinliiniition, an electric lump adapted lo cinit ultra violet rays, a cabinet enclosingt-hc sinne. and a telescoping support for permitting the lmnp to he elevated from within to e position above the saine, said teleeeoping support having therein electrical connections tor the lmnp. i

in testimonyY that I elaiin the foregoing, l have hereunto eet niy hand this 8th dey of April7 1926.
